Problems to Clone existing diagram [message #636933]

In a last post, I asked about to change the editor id of the composite.diagram,
because i want to do a new editor for a new diagram type(a profile uml with his own palette).

For do this, i want to "clone" the composite diagram(renaming the diagram plugin , packages, some attributes in some classes, and changing the editorId) to add a new default custom palette.

I changed the id and the name of packages in the composite.gmfgen, i renamed the source package of oep.diagram.compoiste, and then i regenerated the code from gmfgen.

It works fine, and i could change the diagram id too,but when i launch the plugin and execute the new editor, i can select an element from palette, but i can`t add this to the canvas.

Any suggestion?

thanks Andres

I can resolve the problem.
For do this I change all references(the reference to the custom-src and image file i dont change) to CompositeStructure(MODELID), and composite(name plugin) for my own in the plugin.xml, plugin.properties, gmfgen(i change the extension file too in this file), message.java in custom-src, and then i regenerate papyrus code from the gmfgen.
